Best Air Scrubber for Basement | Top 5 Air Scrubbers, Pros&Cons

Best Air Scrubber for Basement

The odor from basements stinks like rotten eggs, and nobody likes it. The poor ventilation and musty mold are choking since there are no windows to bring in the fresh air and replace the odor.

If you have a smelly basement, you’ll need an air scrubber to clean the air. An air scrubber is beneficial for people suffering from allergies and breathing difficulties. It works best in a disgusting cellar due to stagnant air.

An air scrubber can help circulate clean air in your basement or any part of your home with indoor air quality that falls below the average level.

Improving the air quality in a basement by cleaning with an air scrubber is the simplest way of getting rid of dampness, dust, and musty odors always present in basements.

These negative air machines circulate air through filters and dump the contaminants floating around. The contaminants may include allergens, bacteria, dust, and mold spores. The best air scrubber for a basement comes with features that eliminate pollutants from the basement completely.

The features are Pre-filter, True HEPA filter, and Activated Carbon filter. Combining these features will eliminate up to 99.97% of harmful airborne particles of 0.3 microns, remove the damp smell, and kill germs. 

Let’s consider the factors you must look out for before purchasing a scrubber for your basement.

Top 5 Air Scrubbers for Basement

Buyer’s Guide to Select the Best Air Scrubber for Basement

When choosing an air scrubber for a basement, you need to consider factors that will help in restoration and mold remediation projects.

1. Filtration System

The filtration system is the main feature of an air scrubber for a basement as the filter handles the particles and odor filtration process. Most organic contaminants are microscopic with sizes 0.3 to 100 microns captured by a True HEPA filter only.

A HEPA filter will remove all microbes such as mildew and mold, protects the air with antimicrobial treatment to prevent the contaminants from reforming.

An activated carbon filter purifies the basement of VOCs and odor smells through chemical adsorption. It prevents the musty and smells from clinging to the walls of the basement.

2. Type of Blower

Using an air scrubber continuously causes debris to accumulate on the filters, which will reduce efficiency and airflow to cause static resistance.

Blowers in air scrubbers are for different functions. The Air-foil type blowers overcome the drop in pressure due to dirty filters because it produces powerful airflow to prolong the filter as it starts collecting debris.

3. Durability

Air scrubbers with rotomolded polyethylene housing are known for durability. They can withstand different levels of handling for a long time.

Before making a purchase, always confirm the details of warranty coverage for maintenance or failure of machines. Make sure you get information on operational faults and failures.

4. Power Output

Negative air machines with higher wattage are better because they generate more powerful airflow for the basement.

One unit uses about 3amps, but you might need more than a unit for a large basement. That’s why the GFCI power outlet is provided for some air scrubbers to connect more units.

Turning ON the unit will automatically Power-ON other units connected to it, for a combined power output up to 1035W.

5. Price

Renting an air scrubber is expensive, so it is better to buy your unit, as commercial air scrubbers are better investments for the owners.

The robust high-end unit may be expensive but will last for several years. With your specifications handy, you can still get the best performing air scrubber for your project without breaking the bank.

Go for a negative air machine that can handle your job effectively for the best price. 

6. Negative Air Pressure

A scrubber must achieve the negative air pressure level to be effective in mold remediation. It requires a scrubber with a powerful fan and motor, with a completely sealed body, to maintain the negative air pressure.

Creating a negative air pressure means that more air will leave the place than is entering it. It remains the key to handling dust, fungus, smoke, mold, dirt, and other particles.

7. Airflow Rating

It is vital to consider the airflow rating of an air scrubber for a basement before making a purchase. Cubic feet per minute or CFM expresses the volume of air moved by an air scrubber. Although there is no minimum bar, machines with a higher CFM are preferred.

Eliminating mold from a basement requires a higher airflow rating. Be sure that the scrubber you choose has a rating that is suitable for mold remediation. A scrubber with a 500CFM airflow and above can handle the job.

8. Speed

Air scrubbers come with 2-speed options: single-speed or multiple-speed options. Different applications require different speed modes.

In a multiple-speed system, you can adjust the speed of the machine for the job done. Doing this is more flexible compared to the single-speed system. Also, air can recirculate better with the multiple-speed system.

The single-speed unit is not adjustable for airspeed and may not offer a better air cleaning system. Due to this, you cannot control noise during usage.

9. Portable or Integrated

Before purchasing an air scrubber, you need to decide on the type for your job.

Portable air scrubbers work best for large-scale projects like remodeling, restoration, or mediation. For mold and dust elimination from a basement, a portable air scrubber is most suitable.

The integrated types are installed as permanent fixtures in the home and connected to your HVAC system. It means that they work continuously to get rid of contaminants in your home and maintain fresh and clean air.

10. Coverage

Different manufacturers of air scrubbers always give their recommended maximum coverage area. The figure derives from the CADR ratings, airflow, and ACH (Air Changes per Hour).

Scrubbers with a coverage area of 500 sq ft and above are better for your projects.

11. Energy Consumption

Most HEPA air scrubbers come with a 1/3HP motor calculated as 250W of power and a minimum power cord length of 25 feet. They also have a built-in GFCI outlet to power multiple units. Ensure you check the power ratings before using the outlet. Also, avoid using a power cord extender.
